And we came to Jerusalem and stayed there three days.

and that who ever would not come within three days, according to the advice of the rulers and the elders, all he owned would be lost, and he himself separated from the congregation of the exiles.

Then all the men of Judah and Benjamin gathered themselves to Jerusalem within three days. It was the ninth month, on the twentieth of the month. And all the people sat in the street of the house of God, trembling because of this matter, and for the great rain.
